People put small change on the rough wall of this bar in Villafranca del Bierzo. Not attached, just carefully placed. A nice effect.
The smallest coin you normally see is 10 cents, except in grocery stores where you get copper (colored, certainly not real copper), that is, 1, 2, and 5 cent coins. They are a real pain so it felt great to leave some on the wall.
This was a very pleasant bar with a friendly server. They were open at 8 so we got coffee before our 8:40 bus to A Coruna. She wrapped up some Spanish tortilla (egg, onion and potato pie) for us to eat on the bus.
In the Netherlands they have abandoned use of the 1 and 2 cent coins. Prices are rounded up or down to the nearest 5.
